Reporting assumptions

These choices persist and are added to shared URLs.

Ownership basis

Show the full project inventory before ownership adjustment.

Display scale

Display contained quantities in millions of ounces or tonnes.

Resource treatment

Normalise Resources to exclude Reserves: where a project is flagged inclusive, net Reserves out of Resources so the figure is additional Resources beyond Reserves. Unknown-convention rows are shown as stated.

Resource total

Total Resource includes Inferred (JORC convention). Totals are re-derived from category rows wherever the document discloses them.

Recovery basis

Show the issuer's headline recoverable figure as reported. Lithium-brine reserves already have the brine-processing recovery factor applied; everything else is shown as stated.

Commodity view

Primary view: each commodity in its own contained unit (oz / t).

Current R&R by category

Whole-project rollup at the latest vintage per category: printed project-level rows are preferred, and mining areas are summed (tonnes-weighted grade) only where the issuer prints no project-level row. Per-area and per-source detail in the Current R&R table below.

@ US$ 2,300/oz — Metal price assumption used to derive this estimate.
excl — Stated Resources are EXCLUSIVE of Reserves — they sit on top of the reserve, so decks quoting inclusive resources will show a larger figure (inclusive = this row + the converted reserve).
attrib — Figures are net to the issuer's ownership interest as reported (attributable basis) — NOT 100% of the project.

QA notes:

QA WARN: identical figures to a stored row of the same company/project/area/category under a DIFFERENT as-at date — likely a re-presentation (DFS / annual statement / global MRE restating an already-stored estimate). Keep one operative copy; verify supersession before storing both. QA INFO: recompute differs 4.17% from the printed contained figure, but the printed tonnes/grade/contained are only good to ±12.31% (rounding granularity) — treated as reconciled.
